A test tube is usually made from plastic or glass and is shaped like a long tube. If used for a physics or chemistry experiment, one would use the glass test tube. If used for cultures, one would use the plastic tube and discard after use.
Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
A glass tube is a cylindrical tube made of glass that is commonly used in scientific experiments, chemistry labs, and industrial applications. It can be used for various purposes such as containing, mixing, or transferring liquids and gases. Glass tubes come in different sizes and shapes depending on their intended use.
One day a person noticed that light shone through glass stayed inside the glass. If that glass was in a tube shape then the light was mostly confines to inside the glass regardless of how long the glass tube was. The clearer the glass meant the longer the tube could be before the light became too weak to be useful. Optic Fibre in use these days can literally cross oceans
the mass of glass depends on its size so get a triple beam balance to figure that out buddy
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
with considerable difficulty. I'd use a Dremel with a diamond cutting disc.
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.
